Nobody likes working out, but if you're a celeb, it's part of your job to stay hot. Portia de Rossi is Ellen DeGeneres' hot wife, and Ellen shows us how she stays so hot. Unfortunately, Portia didn't know she was filming her do an old Jane Fonda aerobics tape!

Ellen and Portia are too adorable, and when you hear Ellen's laugh at the end of this quick clip of Portia working out, you'll hear how much fun she had catching Portia while she 'feels the burn'!

Then, Portia decided to get Ellen back, and turned her cellphone camera on an unsuspecting Ellen while she ran to the latest by Bruno Mars!

These are some funny women!
